We're gonna have to do this all by ourselves

Simon Gruber:
This, gentlemen, as they say, is where the plot thickens. I have put 2,400 pounds of explosive in one of the 1,446 schools in greater New York. It is fitted with a timer set to explode at exactly 3:00 p.m. Thank you. Your silence says I'm understood.Inspector Cobb:Did you say 2,400 pounds?Simon Gruber:Yes, but please don't interrupt again. Simon says, if you attempt to evacuate schools, the bomb will be detonated by radio; and gentlemen, someone will be watching. Repeat, one school will be dismissed at 3:00 p.m., permanently, unless...Inspector Cobb:Unless what?Simon Gruber:Unless John McClane and his new best friend complete the tasks I set them. John, are you listening?John McClane:Yeah.Simon Gruber:The pay phone beyond Hope Tompkins Square Park. Twenty minutes. Go by foot; no rush. If you're really clever, you'll learn the location of the bomb and the code to disarm it. Oh, and by the way, gentlemen, we got something of a bargain on radio detonators. The only problem is the darn things seem to respond to police and FBI frequencies. So if I were you, I'd keep off your radios.Inspector Cobb:Simon, wait.Inspector Cobb:2,400 pounds of that liquid stuff. My god. Get me the commissioner.Officer Jane:He's doing a press conference. He's supposed to be here in half an hour.Inspector Cobb:All right, Ricky, get every senior officer on the site and get 'em here right away. You're not gonna give me any jurisdictional nonsense on this?FBI Agent Andy Cross:I got two kids in the school on 64th Street. What can I do to help you?Inspector Cobb:How many men have you got?FBI Agent Andy Cross:75. But if I push the panic button, I can get 500 from Washington.Inspector Cobb:When?FBI Agent Andy Cross:2:30, 3:00.Bill Jarvis, from Another Organization:Between now and then...Inspector Cobb:We're gonna have to do this all by ourselves
